Fluted Toothbrush Cup for IKEA DRAGAN Set

A toothbrush cup that matches my Fluted Cover for the IKEA DRAGAN soap dispenser. It has the same outer shape and the same flutes, framed by smooth bands at the top and bottom. Placed side by side, the two pieces form a matching set. No IKEA parts are needed, the cup is fully printable.

The cup is open at the top and the bottom. A removable honeycomb floor rests on four corner supports 10 mm above the sink. Water drips straight through, and air flows freely from below, so toothbrushes dry quickly and nothing stands in a puddle. The floor is about half open, but with 7 mm cells a toothbrush handle won’t sink in and a toothpaste tube stands on it securely. For cleaning, just push the floor out from below and rinse it.

Features:

• Same design as the Fluted DRAGAN soap dispenser cover: 11 / 7 flutes (R2.5 mm, 1.2 mm deep, 6 mm pitch) with smooth 14 mm bands and gradual transitions

• Removable honeycomb floor, 73 × 53 × 3 mm, with 7 mm cells, 1.8 mm ribs and about 51 % open area

• Floor top surface 10 mm above the counter, resting on corner supports

• 3 mm corner feet that can be printed in a contrasting colour

• Chamfered inner top edge

• Dimensions: 85 × 65 × 122 mm, plus 3 mm feet (W × D × H)

Print settings

Cup

• Orientation: upside down, as provided in the file. The top rim goes on the bed.

• Supports: not needed. The flat faces of the corner supports print as short bridges between two walls and stay hidden under the floor.

• Walls: 4

• Infill: 10–15 %, gyroid recommended

• Top / bottom layers: 5 / 5

• Layer height: 0.2 mm

• Brim: not needed

Contrasting feet (optional): The feet are the last 3 mm of the print. In your slicer’s layer preview, add a filament change at 122 mm, and everything above that height prints in the second colour. On a single-nozzle printer without an AMS, use a pause at the same layer and swap filament by hand.

Floor

• Orientation: flat

• Supports: not needed

• Walls: 2–3, so the honeycomb ribs print solid

• Layer height: 0.2 mm

Material: PETG is recommended for the floor because it stays wet most of the time. The cup can be PETG or PLA. PLA works fine if the cup doesn’t sit near a radiator or in direct sunlight.

Tips:

• The floor has 0.5 mm clearance on each side, so it drops in easily without a test fit.

• Place the seam on a rear corner, where the rounded edge hides it best.

• For silk filaments, slow the outer wall to 30–40 mm/s for an even sheen.
